CHURN.

SPECIFICATION forming part of Letters Patent No. 323,784, dated August4, 1885.

Application filed March. 12, 1885. (No model.)

T0 at whom it may concern:

Be it known that I, JOHN WV. OADY, of Hamiltomin the county of\Vashington and State of Rhode Island, have invented certain new anduseful Improvements in Churns; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

This invention relates to that class of churns that are suspended onpivots and subjected to a swinging pendulum motion, whereby the dasheris moved up and down in the churn through the agency of levers attachedto the supporting-frame.

Figure 1 shows an end elevation of the churn and the improvements. Fig.2 is a top plan View of the same. Fig. 3 shows a side elevation of thewhole apparatus. Fig. 4 is a side elevation with parts of thesupportingframes, and also of the swinging frame, removed to show thearrangement of the interior.

The churn and its working attachments are supported upon a frame, D,which consists of an oblong top frame standing on four legs. In themiddle of each side of the top frame a bearing, a, is placed, to receivethe pivots on which the churn-frame F swings. This frame F is made witha broad bottom, that supports the churn, and two side pieces, whichextend up on each side of the churn to the top, where they are fastenedtogether by a cross-piece, J, that also serves as a guide for thedashers G O. A double bracket, or walkingbeam, as it may be called, B,is attached to the churn-frame F, which it incloses. It has pivotsattached on each side at the middle, which pivots rest in the bearings aand support the churn and swinging frame F. The dashers, of which thereare two, 0 0, have the upper ends of their staves made to slide inopenings in the cross-bar J and also through like openings in acrossbar, E, near the middle of the churn-frame. The staff of eachdasher O O is made in two parts, joined together just above the top ofthe churn with a bolt or other fastening that can easily be removed toadmit of the churn being taken dasher-statf O, and their outer endssupported by pivots G, held in studs on each end of the top frame. Along slot is made in the outer end of each lever A, through, which thesup porting-pivot passes, the object of the slots being to allow of asliding motion in the le vers. The two levers A A rest at about themiddle of each on the outer ends of the walking-beam B, to which theyare confined by the caps L L, attached to the under sides of the levers.

The operation is as follows: The churn j, with a proper quantity ofcream, is placed in the frame F, as shown in Fig. 1. The lower parts ofthe dashers C 0, being already in the churn, are secured to their upperparts, which remain in the frame. The operator, by means of the rod H,which has a hook in its end to catch into a staple in the side of theframe F, gives a swinging pendulum motion to the churn and frame F. Asthe frame F swings to one side, the arm of the walkingbeam B on thatside raises the middle of the lever A on that side, and as the outer endof the lever is held by the pivot in that end the inner end of the leveris thrown up, carrying with it the dasher that is attached to it. At thesame time the other end of the walking beam B is depressed, and by thedownward motion of the lever A on that side the dasher attached isforced down. ing motions back and forward the two dashers are made tomove up and down past each other in the churn with great effect. Theeasy swinging motion of the frames, the two dashers balancing eachother, together with the momentum of frame and churn, with its contents,combine to produce a great effect with a comparatively small exertion ofpower by the operator. The motions of the dashers in the churn slidingpast each other are very effective in churning the cream and in workingthe butter together in one mass after it has come.

Having thus described my improvements,

By successive swingwhat I claim as my invention, and desire to se- Inwitness whereof I hereunto set; my hand. core by Letters Patent, is
